I don't understand the question. What do you mean by "cycle
time"?

Sure. 10ms is just the timer tick frequency. The only thing
it affects is the granularity of things like cyg_thread_delay().
If your thread is blocked waiting for a frame, it will wake up
when the frame arrives regardless of the system timer tick
period.
